CLICKING-MACHINE.

Specification of Letters Patent.

Application filed July 25, 1914. Serial No. 853,212.

To all whom it may concern:

Be it known that I, CHARLES H. ROPER, citizen of the United States, residing at Belmont, Massachusetts, have invented certain new and useful Improvements in Clicking- Machines, of which the following is a specification.

My present invention relates to improvements in machines for cutting out thin sheet material and particularly to machines of the type known to thetrade as clicking machines. Such machines cannot be made to operate over wide stock, such as it is desirable to use in making fabric uppers, without making them too large and cumbersome, or making the cutting block movable, which latter is unsatisfactory owing to the excessive pressure to Which the cutting block is subjected.

The object of the present invention is to provide a clicking machine with simple, economical and efficient means by which stock.

wider than the cutting block may be readily out throughout its entire width, and the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended Claims.

The invention is illustrated by aid of the accompanying drawings in which,

Figure 1 is a side elevation showing conventionally the cutting block and presser head or member with my improved sheet holding and shifting means applied thereto. Fig. 2 is a diagrammatic plan view, the presser head being omitted from this view. Fig. 3 is a front view of the sheet holding and shifting mechanism. Fig. 4 is a detail view.

Referring by reference characters to this drawing, the numeral 1 designates the cut,- ting block or table, and 2 the presser head of an ordinary or any desired form of clicking press, the matter of operation of which being well understood by those skilled in the art, need not be particularly described herein. At one end of the cutting block I place an extension shelf 3, flush with the surface of the cutting block and extending therei guideway comprising a pair of rods or bars 4, 4, on which is Slidably supported stock holding means; This includes a Shelf or tray 5, which receives the uncut stock and which is supported by brackets 6 from the members or carriages 7 slidably mounted on the rails 4. Uprights 8 are adjustably supported from the lugs or projections 7 a of these carriages, preferably by nut and screw thread connections as shown. At the upper ends of these rods are secured heads or brackets 9 to which is attached the bar 10 constituting one of the members of the stock gripping jaws. Levers 11 are pivoted to lugs 12, projecting upward from the brackets 9 and these levers carry a bar 10, which constitutes the other gripping jaw. The jaws may be normally drawn together to grip the stock by springs 13 and opened by a rod 14 connected at its upper end to the end of the lever 11 and at its lower end to a treadle frame 15 pivotally supported by brackets 16 from the brackets 6.

By the apparatus above described, and

supposing at the start the parts to be in the position shown in full lines in Fig. 1, after the full area of the cutting block has been cut over, the stock carrier and holder is shifted to the opposite end of thesupporting rails, bringing the uncut portion of the stock or that between lines a-b over the cutting block and within the range of the presser head.

Having thus described my invention, what I claim is 1. In combinationwith the cutting block and presser head of a clicking machine, an extension table or shelf at the side of said cutting block and stock holding means shiftable'with relation to said table and shelf.

2. In combination with the cutting block and presser head of a clicking machine, stock holding means in proximity to said cutting block and having a length in excess of the from said track, and means for operating 10 length of the cutting block, and shiftable in said grippers. relation thereto. In testimony whereof, I afiix my signature 3.. In combination with the cutting block in presence of two Witnesses. 5 and presser head of a clicking machine, a

horizontal track, a support for uncut stock CHARLES ROPER' slidably supported from said track, stock Witnesses:

gripping means in proximity to the edge of L. E. MARR,

the cutting block and also slidably supported E. A. HEALY.
